Gas detector
There are many gas detectors on the market that are seemingly identical, but a closer look at their specifications and characteristics can highlight key differences in what they can offer. Besides that, specific applications require special detector configuration which is also something to consider.
Before considering gas detection equipment, it is necessary to conduct a risk assessment. Particularly, the working staff is obliged to make a risk assessment in order to identify potential hazards, which includes the risks of potential gases, vapors and oxygen deficiency. If hazardous gases are identified, gas detection is an acceptable method of risk reduction.
Depending on carried out activities and detected gases, potential selection requirements may include recording activities and data as well as notification in the case of an alarm activation.
The risk assessment identifies gases that need to be detected. However, manufacturers of gas detection equipment can evaluate an adequate solution for the user based on experience and previous applications. It is important to remember that it is the responsibility of the end user to estimate all potentially hazardous gases. It is also important to identify a potential source of gas leakage as this helps to estimate the number and location of detectors for fixed detection systems.
Temperature, humidity and pressure are physical quantities that should also be considered as they affect the performance, accuracy and reliability of gas detection systems.
The next thing to consider is the functionality of the detector. The wiring of the detector as well as the communication protocol used must be taken into account if the detector is integrated in a separate safety system (e.g. HART, Modbus).
Regular maintenance of the device is also an important factor when choosing it. For example, catalytic sensors will require more frequent maintenance than Non-Dispersive Infrared Detection sensors.
